Glacier Research

~ Saturday 20th September 2008

I've been helping with some research on the Haut Glacier d'Arolla, investigating melting rates. We drilled some holes 50cm into the ice and set up measuring poles, then marked the ice surface level. I then set off to walk the Haute Route.

Returning yesterday to collect the poles after a week of cold snowy weather I expected to see very little change, but....

Measuring pole, black line shows original surface level


The black line shows the surface level 10 days ago, with a change of 10cm. So 1cm/day in a period of cold snowy weather - there was 5 cm of fresh snow here the previous night.
